While 85% of women were satisfied with the size and proportion of their partner's penis in a study, men were less sure of themselves. 45% of men in the study believed they had a small penis. Across studies it has been concluded that flaccid lengths range around 7 to 10 centimeters (2.8-3.9 inches).Flaccid circumferences range around 9 to 10 centimeters (3.5 to 3.9 inches). Erect lengths range around 12 to 16 centimeters (4.7 to 6.3 inches).Erect circumference (only one previous study) was around 12 centimeters (4.7 inches). I visited hashmidawakhana.com and tried sikander-e-azam plus capsules as suggested by my best friend. I have noticed a considerable increase in my penis size. I have gained 2 inches in length and almost half inch in girth.
